taken on the line a: x, Fig. 2.v

Be it known that I, WASHINGTON IRvING AVERY, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Water Stills and Condensers, of which the following is a specification.

This invention relates to water stills and condensers; and it has for its object to provide a simple and improved device or apparatus of this class which will be comparatively inexpensive in construction and of high capaci tyand efliciencyand which will effectively operate to thoroughly aerate the condensed water.

In the drawings forming a part of this Specication, Figure l is a side view, partly in section, of my improved condenser. Fig. 2 is`a vertical longitudinal sectional view. Fig. 3 is a top or plan view, the cover being broken away. Fig. 4 is a horizontal sectional view Fig. 5 is ahorizontal sectional view taken on the line y y, Fig. 2. Fig. 6 is a horizontal sectional view taken on the line c' c, Fig. 2. Fig. 7 is a horizontal sectional view taken on the line Fig. 2. Fig. 8 is a horizontal sectional view taken on the line 1/y', Fig.` 2, and looking upwardly. Fig. 9 is a detail perspective view, partly broken away, of the valve means for controlling the automatic water-feed from the water-reservoir.

Corresponding parts in all the figures are denoted by the same numerals of reference.

Referring to the drawings, 1 designates a boiler which has a top opening 2, surrounded by an annular flange 3, and may be provided with a suitable inlet or feed tube, as at 4. This boiler is designed to contain the .water to be distilled and purified and aerated, and it is adapted to rest upon a stove or other heating apparatus. In lieu of the boiler l an ordinary tea-kettle may be employed. To increase the heating efficiency of the boiler, it may be provided with a conical bottom, as shown at 5, forming a hot-airchamber 6, having at its apex radial outlet-tubes 7, extending to orifices 7a in thesidesof the boiler.

8 designates a drum or chamber for the condensed water, which is supported upon the boiler 1 and detachably connected therewith by means of an annular iiange 9, surrounding the bottom opening 10 of the drum and fitting within the flange 3 of the boiler. The drum is provided with a conical bottom 1l, extending from the bottom opening 10 and forming a tube, which provides a convergent steam-outlet from the boiler, and the drum has a suitable faucet 12 for drawing o the distilled or condensed and purified water.

The drum 8 carries a set of vertical con= densing-chambers 13, extending upwardly from the top 14 of the drum, which chambers are preferably arranged in an annular series, as shown,for purposes of strength andconvenienceiand economy in space. The con-v densing-chambers communicate at their lower ends with the condensed-water drum byY means of openings or perforations, as at l5,`

formedin the top 14 of the latter and arranged in radial series to intersect the condensingchambers.

openinto the drum; butIpreferto employthe inlet perforations or openings 15, as shown, inasmuch as it is desirable to cut up the passage of the steam to facilitate condensation.

To effect thorough aeration of the condensedwater, an air-inlet is provided in connection with the condensing-chambers. This air-inlet comprises a chamber 16, provided above the boiler and between the latter and the condensed-water drum in the space formed by the neck-flanges 3 and 9, the sides.' `of said air-chamber being preferably formed.

of aforaminous or network iiange 17, car'- ried by the drum 8 and projecting down- Wardly therefrom. The provision of an initial air-chamber above the boiler and the inclosure of said chamber by foraminous or perforated sides causes sterilization of the Vair before its passage to the condensing- The whole area of the lower endv of the condensing-chambers may, if desired,

roo

cal tubes 1,8, passing through the drum 8 and having their lower ends opening through the.

the'lower portion ot' the ,condensing-cham@ bers, the air being thus further initially introduced to the condensing-chambers at a high temperature and sterilized by reason of the contact of said feed-tubes 18 with the condensed waterin the drum 8. per ends the tubes 18 are extended laterally and horizontally, as at 20, and open laterally within the condensing-chambers, as at 2l', whereby passage of the condensed water intov said air-inlet'tubes is precluded.

, 4 Upon the top of the series of condensingchambers 13 is mounted a steam-chamber 22 with which the upper ends of the condensing.- chambers'communicate, preferably by means oflopenings or perforations 23, formed in the bo 'bm 24 of the top chamber 22 and arranged in radial series to Yintersect the condensing-l chambers'. A suitable detachable cover, as at 25, is provided for said top chamber and is preferably deine-shaped, so that it forms i-nteriorly'a dome-.space 26 at the top of the chamber 22for the steam. Within the chamber 22l .is arranged a water-reservoir 27, the v relative .construction and arrangement being such that a space, as at 28, exists between thebotto'm 29 ofl the reservoir 27 and the bottom 24 of the chamber 22 and also between the sides or walls of the reservoir 27 and champ; bei: 22, as at 30, which spaces provide a passageifer the steam from the condensing-charnbers 13. around the reservoir 27 andv to the dome-space 2G, The reservoir 27 is designed to contain feed-water tor supplying theboiler,

i and `inoperation this feed-water willv be initially heated and also partially supplied with condensed water before feeding to the boiler,

and itis aerated by action of the steam and y A feed-pipe 31 extends from the reservoir 27 downwardly and through the condensed-water drum 8 and air-chamber 16 andinto the boiler 1, said pipe being preferably centrally arranged, so that itis central with j respect `to theseries of condensing-chambers y passes through the bottom opening of thefennd'ensed-water drum and through the topiop'ening. of the boiler. It will be understood'that the water will automatically feed by gravity through the vertical pipe 31 from the reservoir-27 to the boiler, and suitable valve means are provid ed to control and regulate this feedY of the water so that theautom-atifc feed of water to the boiler will correspend tothe amount condensed and deposited inA the drum S. The valve-control may consist olf-an extension, as at 32, of the top end or thepijpe31 above the bottom of the reservoir 27,"the wall of which extension may have an inlet slit or slot, as at 33, and said extension receives a tubular key-piece 34, extend- At their upingabove'the level of the -water inthe reservoir and having in its wall a slit orslot, as at 34:', adapted to register with the slit or slot 33.

To augment the deflection of the passage of the steam upwardly in the condensingchambers-lS, whereby condensation isfacilitated, I provide' laterally-projecting or downwardly curved or turned blades or wings 35, carried upon a strip or krod 36, mounted in a vertical and longitudinal position within the condensing-chamber 13. The strip andvits blades may be effectively formed of scraptin? simply cut and turned to prod ucel curved delecting-blades. l

' It-will be noted that the bottom and top openings, whereby the condensing-chambers communicate, respectively, with the condensed-.water drum and the Vtop steam-chamber,are preferably of varyingsize ordiameter,the outer openings being relatively larger, as represented at 37, than the inner openings, as represented at 38, Fig. 8. The result of this structure in practical operation ,is that the heated steam will rush quickly upward in the condensing-chamber and out at the inner smaller opening 3S, immediately under 'and against the bottom of the feed-water reservoir, thus highly heating the water in said The separated, which quickens the action of the condenser, and the quick upward rush of the het steam draws the airand thoroughly causes fu'll and complete aeration.

Furthermore, the upward rush of the hot or super-heated steam against the bottom of the top waterreservoir, as above mentioned, wil-lso highly heat the water insaid top reservoir that the ,same will generate steam and condense, and

'boiler land at thetop of the device from the `feed-water reservoir.

sterilized air in the chamber 22 and domespace'26.

The boiler l may,ifdesired,be provided with a set of'vertical fines, as at 39, Fig. v2, ar-

; ranged in circula-1.' series surrounding the cen-y tral cone and open at the bottom, as at 40, the top end of said lues having a vent-.opening hanced and rapid action and economy in the heating medium are insured.

In the top dome may be provided au airventas at 42.' y f In operation the steam generated in the boiler passes through the cone 11 into the drum 8 and through the openings 15 into the condensing-chambers 13, and the steam is cooled by the atmospheric air surrounding said chambers. The steam also passes from the condensing-chambers 13 through the openings 23 to thev top steam-chamber 22 and is cooled by the atmospheric air in contact with said4 chamber 2` and its dome-top 25. The top reservoir also operates to: generate steam in the dome-topY 25. The products of IOO IIO

condensation in the form of thoroughly-purified water trickle or iiow back through the condensing-chambers and are accumulated in the reservoir drum orreceptacle 8, as will be readily understood.` The action of the steam in its upward passage draws air into the airchamber 1G, Where it is sterilized by the heat from the boiler, and into the condensingchambers and top steam-chamber 22, wherein the air is further sterilized by contact with the steam, thus effecting a thorough admixture of a large quantity of sterilized air with the steam, which not only accelerates condensation, but also thoroughly aerates the puried water resulting from condensation.

The relative construction and arrangement of my improved apparatus are such that a quick action in condensation andconsequent high or maximum capacity are insured.

The still may be supported on a suitable perforated ring or on legs, so that When placed upon a stove air will circulate beneath the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
